fix(hooks): propagate lint-staged exit code from husky pre-commit

The wrapper ran 'bun run lint:staged' and then unconditionally printed
'✅ Pre-commit checks passed.' regardless of the exit code, so failed
eslint-fix runs (which lint-staged handles by reverting all task
modifications, including prettier --write) silently let unformatted
or lint-failing blobs land. Add 'set -e' so a non-zero lint-staged exit
aborts the commit, which is what every other contributor expected.
